If the latest driver didn't solve it, I'd start looking elsewhere at what the problem could be.
It could be some program you have to start with Windows, possibly from the motherboard manufacturer. It could be other software making internet connections that is running and not working so well.
Check the event logs for anything suspicious or related. Alleviate those problems and this might go away with them.
Ups. I forgot to mention. This happens without any third party involved. No other SW was installed beside Win7 and of course Wireshark to do some packet traces. BTW: based on this and other quirks our company shelved Win7 (as they did with Vista before). Even no testing are ongoing in the labs anymore. Oh well may be SP1 will be reconsidered. If not - may be Win8 or 9 or... (hope M$ is still around then).
the strange thing is when i installed and tried to surf on windows xp mode on windows 7, it works pretty well. Even my internet connection is gone on windows 7, it works like charm on windows xp mode. i hope MS will solve this problem or I will be have to go back to xp or vista
I had the same problem. The solution that appears to work:
Under "Device Manager / Network adapters / Marvell . . . / Advanced" tab:
Energy Star: Disabled
Wake From Shutdown: Off
Wake-Up Capabilities: None
Any combination of the three might be the culprit. The leading culprit would be Energy Star. I can see where the OS would turn off the port after inactivity but fail to turn it on when activity resumes. Either Microsoft or Marvell didn't implement the feature correctly.
